This study focuses on RR, SS and RS medetomidine (MM) and inclusion of several achiral acids to distinguish which acid can help conglomerate formation instead of crystallizating racemic mixtures by defining the low-lying energy of their structures. Favorable orientation of acids was determined in interaction with the MM enantiomers after optimization. The most noticeable interactions include hy...
The elusive biaxial nematic liquid crystal phase was recently discovered in a family of substituted oxadiazoles. Our investigations of these materials show that the achiral biaxial nematic phase can segregate into chiral domains of opposite handedness, thereby demonstrating that the liquid-like nematic phase exhibits the properties of a conglomerate.
Conglomerate formation, where enantiomers within a racemic mixture self-segregate upon crystallization, is an advantageous property for obtaining chirally pure crystals and allows large-scale chiral resolution. However, the prevalence of conglomerates low difficult to predict. In this report, we describe our attempts engineer from racemate-forming compounds by integrating them into conglomerate...
one of the popular ways of taking advantage of personnel creativity is through suggestion systems. our main question is how to implement suggestion system in holding with conglomerate structure. the paper presents an innovative model that were named itfsk model with accordance of bonayade taavone (a holding that has many companies and institutions with conglomerate structure). itfsk is a model ...
We examine the effect of financial dependence on the acquisition and investment of singlesegment and conglomerate firms at different stages of the industry life cycle. Conglomerates and single-segment firms differ in acquisition activity more than in the level of capital expenditure across all stages. Financial dependence, a deficit in a segment’s internal financing, decreases the likelihood of...
Silicosis is the most common occupational lung disease worldwide. It leads to respiratory impairment and may have associated infections that decrease pulmonary function. We describe the case of a 55-year-old man with chronic silicosis who presented with hemoptysis and a cavitated conglomerate mass. The final diagnosis was silicotuberculosis.
The first bent-core molecules comprising 4-iodoresorcinol as the central core unit and incorporating azobenzene units have been synthesized. A new type of dark conglomerate phase (DC phase) is observed, which remains over a wide temperature range down to room temperature without crystallization.
